Abstract:
Heavy metals in drinking water pose a threat to human health. Populations are exposed to heavy metals primarily through water consumption and few heavy metals can bio accumulate in human body and may induce cancer and other risks. Quantitive determination of five heavy metals (iron, manganese, Nickel, Lead and Cadmium) in five water samples collected from Tarahara, Itharai sub-metropolitan city was carried out by using atomic absorption spectrophotometry by standard method (APHA-3111 B, 1998). Physical parameters (pH, Conductivity, Temperature and TSS) were also measured in the tested samples. The analysis showed that the concentration of Iron and Manganese were found higher whereas Nickel, Lead and Cadmium were found within the standard limits given by NDWQS in tested samples of water. All the values of physical parameters were within the range specified by WHO guidelines of drinking water.
